PICKING MECHANISM FOR LOOIYIS.

Application filed January 3, 1918. Serial No. 210,156.

To all whom it may concern: I

Be it known that I, ARTHUR NnW'roN- SMITH, a subject of the King of Great Britain and Ireland, and resident of Westminster, England, have invented new and useful'lmprovements in Picking Mechanism for Looms, of which the following is a specification. I

This invention relates to improvements inthe picking mechanism of looms, and is applicable to overtype picking'mech'anism, and also to undertype picking mechanlsm of the class or type in which the pickeris connected with the picking stick'by'a pickg v effort is 50 applied are described and claimed ing strap and is thus indirectly acted upon by the picking stick. 1

The invention has for object to overcome or minimize certain disadvantages which pertain to pickers as ordinarily mounted on the picking spindle.

The invention consists in the provision'of' what is herein called a duplex picking spindle and in mounting the picker thereon.

In picking mechanism for looms, in' accordance with this invention, the picking spindle comprises a pair of rods mounted parallel with one another and carried by the spindle stud and the end plate of the shuttle box, the picker being mounted and movable along both of said rods.

As will be obvious, the invention can be carried into effect in various ways, and in the accompanying drawings, which are to some extent diagrammatic and are illustrative only, several arrangements are shown. Figurel is a sectional elevation-a1 View of one form of the device, and Fig; 2 is an end view of the spindle stud;

Fig. 3 is also a sectional elevational view of a modification, and Fig. 1 is an end'view of the end plate of the shuttle box; and

Fig. 5 is a sectional elevational view of another modification.

Referring to Fig. 1. V V

1 is the. end plate of the shuttle box and 2 is the spindle stud. ordinary arrangement, would form the picking spindle. The rod 3 is mounted in the same manner as is pickingspindle, that is to say, one end is contained and carried by the spindle hole in the spindle stud 2, the other end passing through a hole in the end plate 1 of the shuttle box and being acted upon by the spindle spring 4. 5 is another rod, and parallel with the rod 3; the rods 8 is a rod, which, in the 3, 5 constitute what has herein been called a duplex picking spindle.-

In the arrangement illustrated, the rodl5 is shown as mounted below the rod 3. "The disposition of the rods 3, 5 will depend upon the construction of the picker employed and upon other considerations based upon the construction and dimensions of the loom. The picker employed may be of any suitable construction, butpreferably one of the kind in which the picking eli'ort is'applied thereto coaxially with one of the rods 3, 5 or as near as possible to the shuttle, is employed. Pickers in which the picking in the specification of another application for Letters Patent No. 6045, dated 28th April, 1917, and such pickers when mounted on a duplex picking spindle in accordance with this invention have the picking strap attached to, or connected with, a part of' the picker that embraces or surrounds one of the rods as shown in Fig. 1. 1

In the arrangement illustrated in Figs. 1 and 2, the rod 5 ismounted at its ends in disks 7, which in turn, are mounted on the rod ,3, wh ch 1S mounted as ordinarily. The

disks 7 and 7 are rotatable about the rod 3 and can be secured in any desired position ends 'and'mounted, respectively, in the end plate 1 of the shuttle box and in the spindle stud 2". In this modification, the ordinary spindle hole in the spindle stud 2 is bored through and receives thebolt 13 which is maintained in position by a nut 1 1. The bolt 12 is under the action of the spindle spring 1 outside the end plate 1 in much the same manner as is the ordinary picking spindle, so that the rods 3 5 are forced toward'the spindle stud and kept in the desired position. Instead of employing a spindle spring 4 to act on the end of the bolt the 'ends oi the rods 3 '5 are both mg means.comprising,for example and as plex picking spindle; being moved angu-- 12, the mountingof the bolt 12 may be modi- I are such that they permit a picker 6 to be .10

employed with shuttles of various sizes, that is to say, they permit or the picker and dularly, and as such movement producesa vertlcal and horizontal ad ustment of the part ofthe picker which receives the shuttle impact, that parti's accommodated to various heights and widths of shuttle.

I With pickers mounted on duplex piclr; mg spindles, the tongue or picker foot ordinarily employed to prevent angular displacement is or may be dispensed with,

may be the groove or slot in the fiy plate.

' What I claim is 1. In a picking mechanism for looms, thecombination with an end plate of a shuttle box,of-a spindle stud, a picker disposed between said end plate and said stud and means foradjusting the angularposition of the picker.

2. Ina picking mechanism for looms, the

I combination with an end plateof .a shuttle picker 7 4t. Ina

box, of a spindle stud, a picker disposed be- 7 tween said end plate and said stud, said;;. picker being rotatable to different angularpositions toaccommodate shuttles of differs; ent sizes "and means {for holding the pickerv in its adjusted position.

3. In a picking :IllGCllZtlllSlIl tor looms, the

combination with'an end plate of a shuttle box, o'f a spindle stud, a pair of parallel rods, a picker suported by said parallel. rods and means for shifting the relativepositions of said rods while maintaining the latter parallel, to, vary the angular position of the icking mechanism for looms, the

combination with an endplate of a shuttle box, of aspindle stud, apair of parallel rods, a picker supported by said parallel rods, means for shifting the relative positions of said rods while maintaining-the latter parallel, to vary the angular position of the picker and means for securing the, picker in its adjusted positions. 1

5. In a picking, mechanism for looms, the

I combination with an end plate of a shuttle box, of a spindle stud, a pair oi' parallel rods for supporting a picker, a disk pivotally mounted on said end plate, each of said parallel rods having oneend secured to said up hold disk,'the opposite ends of the rods being secured to said spindle stud.

6. In a picking mechanism for looms, the

combination with an end plate of a shuttle box, of a spindle stud, a pair of parallel rods for supporting a picker, a disk having a central pivot-bolt extending through said end" plate, said pair of parallel rods being disposed on opposite sides of the axis of said pivot-bolt, each of said parallel rods having one end secured to saiddisk and the otherend secured to the spindle stud.

7.,In a picking mechanismfor looms, the

combination with anend plate of a shuttle box, of a spindle SlI-l1Cl,' 2t pair of parallel rods for supporting a picker, a disk-havr ing a centralp1vot-boltextending through said end plate, said pair or parallel rods being'disposed on opposite sidesflof the axis of said pivot-bolt and at equal distances therefrom, each of said parallel'rods having one end secured to said diskand theother' end, secured to the spindle stud] 8.

each ofsaid parallel rods haying one end] secured to said disk, and-the other end se cured to the spindle stud and means for se-' curing the pivot-bolt, in different angular :positions', 7 H 9. In a picking mechanism for looms, the

combination with an end plate of: a shuttle box, of a spindle stud, a panof parallel rods forsu ortin av icker a disk-havin a central pivotbolt extending" through said end plate, said pair of parallel rods being secured to saidv disk, and the other end sedisposed onopposite sides of the axis of said pivot-bolt and at equal distances therefrom, each of said parallel rods having one end a cured to. thespindle stud and means forse- V curing the, pivot-bolt. in difi'erentTangular' -positions,;said means comprising a. nut so cured to a threaded end or" saidpivot-bolt and arranged to engage sald end plate.
